Ankle Stability and Movement Coordination Impairments: Lateral Ankle Ligament Sprains Revision 2021

J Orthop Sports Phys Ther. 2021 Apr;51(4):CPG1-CPG80. doi: 10.2519/jospt.2021.0302.


This revised clinical practice guideline (CPG) addresses the distinct but related lower extremity impairments of those with a first-time lateral ankle sprain (LAS) and those with chronic ankle instability (CAI). Depending on many factors, impairments may continue following injury. While most individuals experience resolution of symptoms, complaints of instability may continue and are defined as CAI. The aims of the revision were to provide a concise summary of the contemporary evidence since publication of the original guideline and to develop new recommendations or revise previously published recommendations to support evidence-based practice.
